To all whom 'it may conccr'nf Be it'known that I, Hmmm) T. HALLo- WELL, a citizen of the United States, resid; ing in Philadelphia, Pennsylvania, have in-j vented certain Improvements in Shaft-Collars, of which .the following is a specification. i My invention relates to the constructon'of I an annnlus, such as a shaft collar; and the? object of my invention is toform a shaftv` collar of a plurality of lsheet metal memhers pressed'into the desired shape and soj` constructed as to maintain in properposi-i tion a suitable nnt or othery support throughf which a set screw is passed for normallyf retaining such annnlus or collar in place! upon a shaft or other similar element. My present invention, which is a divisioni of my applications for patents filed 'Marchi l Specification oil Letters Patent.

Original applications led March 20, 1908, Serial Nos. 422,317 and 422,818.

SHEET-:COLLAR .L1-atenten oct. 3,1911,

Divided and this app'ucauon serial No. 446,478.

In the structure shown in Figs. 1 and 2, I .provide a pair 'f members having in cross- 'seetion an L-shaped contour which are eom- "bined to form an annulus o1l collar. These sections have side Walls 1, which may or .may not be offset, and outer peripheral walls or flanges 2. In order to secure this cllai' together, I provide an annular band or sleeve 3 disposed inside the sections f or'ming rthe collar -and lying against the outerpei ripheral Wall of the collar; such bri-tid" or `sleeve being apertured at et for the passage of a set screw 8 and counterbored'to accomfmodate the head ofthe same, in line with a rsimilar aperture in the peripheral walls o1' -flanges of the sections formed by theregister# ing notches 5 therein.

In order to confine the sections in posi 2o 190s, serial NOS. 422,317, and 422,318, fri; crsinore particularly to structures secured together by riveting one'portion' of the'same vvith'respeet to another, alt-liough'as will be readily understood, other means of securing the sections in proper relative position may he employed and are vWitliin'tlie sc opeof inventio My invention is fully shown in the accom panying drawings, in which:

Fi 'ure l., is a vertical sectional View of, one orm of shaft collar made in accordancel with my invention; Fig. 2, is a cross sectional view of the saine, taken on the line o o, Fig. 1; Figs. 3 and 5,'are sectional News of the same character as Fig. 1,.1l1us- Q tratin'g.mocheations embodying my inven g Ytion by said sleeve, the latter may be pro- ,.'vided with ,spuds 6' arranged to enter aperltures 7 in the side Walls 1 of the sections and be riveted thereto, in the manner clearly shown in the drawings; suoli action binding against displacement. If desired, the'b'and ed, or otherwise permanently secured toi tht'- ssections. In the present instance, the, sec-l tions ol* the collar have their /sharp vcorners rounded or beveled. The seourin" sleeve v3 vmay be formed into the neoessal s ape :from Aa fiat strip, the meeting edges .'o whieh abut, fand they may or may 11o/t be `securedirq/fierezing, Welding, or other desirable means. stead of employing an annular band ereleeve tiong'Figs.' 4 and G, are sectional views, taken `on' the'lines b-J and o o, respeo;l tively, of Figs. 3 and 5, and Fig. 7 is a vievvr illustrating a' detail of my invention.

All the structuresyorming the subject of my invention comprise sections' or' blanks of sheet metal. Ipressed into shape to form an, annular member Withshaft engaging por tions; the side Walls 'oft'he members ormr ing the collar having circular apertures for. ythe assage ofthe shaft., arid the'edges of ther Wall; in which said'apertures are'formecill engage said shaft. .The several sections ofi the collar are so disposed as to provide mutual conneetionand, support, and portions of the metal oomprisinggoe or more offthe same are displaced at the necessary points so as to cnneiirifp'iop'er relative osiftion Sa's shown in Figs. l and 52,'1 may usesmli pl/ates 10 such as illustrated 'in the=.I')eli's.}eo.L "tive view, Fig. 7 for the purpose of securing fthe sections of the'collar together, or rivets pf the ordinary tvpe may be employed.

f Instead of spuds passing entirely through the side Walls to be riveted on thejolltsidf the same, they may only. touch said side Walls, and the edges of 'the inner 4bandiniay be electrically wel ed 'by means4 of slight raised Contact points or projections similar t`o spuds, but of smaller proportions. The tint or support 9 through which. the set iscrew passes is laid adjacent thesections .form-ing the collar during the process 'onally securing the same together, and to retain this n ut in lace, l may provide "various means, such or instance as isp'laoh :uitable nut Vfor the set screw emp oyedgwjthf such collars;

" ingthe metal ofl the Walls of the sections "forming the shell by suitable means, as.

tor sleeve 3 may be brazed, electrically Weld A Aso` the 'sections 'together and holding themclearly shown at 11 and\ 2 in the several views of the drawings, t Ve screws 'being broken away in Figs. 2, 4 and 6, to clearly show the piojcclidns 12. l,

ln Figs. il and al, I have sdiown' a structure comprising a pair of L-shaped sections, each having side walls la and 1* and outer peripheral, wal ls 2 and 2"one of said sections being less in diameter than the other so tlifat it may enter the larger section and be suitably secured thereto. As shown in the tilra'wings, such securingis accomplished by means of spuds 6 proyecti'ng from the edge of, 'the peripheral wall 2* of the inner memberiand arranged to pass through apertures iii the side wall l. of the other nieu bei: adjacent its peripheral Wall. It will be understood, however, that the sections may be secured by blazing, Welding, or other suitable means. This form of structure will be provided with a nut in the same manner as the other forms, and the peripheral wallpof the collar -formed by the several peripheral walls of the sections will be provided with the counterbored aperture for the head of said sot screw. To hold the nut in place, the peripheral wall of the inner section will liai'estruek-up portions as indicated al' l1, Awhile the side walls will be struck-up in the manner indicated at .12, .underlying the uut and preventing radial iuoreiiient of the saine.

ln Figs. 5 and 6, l have shown a structure somewhat similar to that shown in Figs. and 4, exept that the inner section is se-u cured by slightly turninr over the edge of 'the peripheral wall 2c' oil'74 the outer section against the side wall ld of the inner section. The nut will be hold in place in precisel the saine manner as the structure shown in igs. and 4, and the inner edge of the peripheral [lange 2 or wall of the inner section or member may be brazed, electrically welded, or otherwise secured to the side wall 1 of the outer section or member.

.ln completin the aniiu'luso shaft collar,

i the membes o, the same are assembled in a suitable 'uannerg the nut beipg properly ositioned and maintained in ch positipn liy moans of the set screw, or a suitable pin, which is passed through the apertures of the several members and then the members are riveted together, the nut having been positioned by displacing the metal of the annu lar baiulor the peripheral. wall of one ot' the incinlici's relatively thereto, in the man ner described.

I may, il desired, in addition tothe riveting, brazo or eloulriially Wold any-a'nil all oi the abutting faces of the several forms of structures shown heroin, and l ma fur- .,llier harden the side wall or face of tio rcspective collars which comes opposite the work. In all instances the strip used as the inner securing collar or sleeve may be made of fiat metalwwith its abutting ends brazed or not as desired, and while-the outer seourin sleeves may also be made of `such metal, t e abutting edges of the saine are preferably brazed. i f

It may be desirable to rovide nuts with curved upper faces to fil the space above the same under the peripheral wall, such( for instance as shown in my companion case". filed herewith. The apertures in the outeilf wall of the collar receiving the set screws are preferabl eountersunk or bored' to ae commodate tl e heads of the set screws so that the latter will not project radially beyond the peripheral face of the same.

I claim:

1. The combination, in a sheet metal shaft collar, of a plurality of sections `l..-shape:l in cross sec'tion, each comprising a'sidevwall and an outer annular or peripheral wall, the side walls of said structure being apertured for the passage of a shaft and each presenting a narrow annular' edge for engagement with the shaft when the collar is applied thereto, means for securing said sections tovether, a nut disposed in the space formed by the walls of said sections, and a set screw 'mounted in said nut, said side Walls having struck-up portions .directly adjacent the shaft opening underlying and supporting said nut.

2. In a sheet metal shaft collar, the conibination ot' a pair of L-shaped members each having a side Wall and an outer peripheral wall or flange with the edges of said latter walls abutting, confining means disposed within said collar to which the sec tions are riveted, said confining means lying against the outer walls or flanges of the sections iind fortuin withthe saine the peripheral `Wall of t e collar, a nut disposed between the side walls of the structure, and a set screw therefor', said side walls being aperturcd for application to a shaft and. each presenting a narrow annular edge l'or ougagenient with the shaft when the collar is applied thereto with portions struck u from side walls dii'eotly adjacent the slia -t opening to underlie and support the nut, andthe outer annular or peripheral wall ot the collar having au enlarged apertui'r` to accommodate the lieail of the-set screw.
